Abstract

RIVERA, Ivan Romero et al. Echocardiograph pulmonary venous flow patterns in congenital heart defects with increased pulmonary flow. Arq. Bras. Cardiol. [online]. 2007, vol.88, n.4, pp.396-401. ISSN 0066-782X.  http://dx.doi.org/10.1590/S0066-782X2007000400005.

OBJECTIVES: To describe pulmonary venous flow patterns using transthoracic echocardiograms on children suffering from different congenital heart defects with increased pulmonary flow. METHODS: Prospective study and consecutive selection of children suffering from congenital heart defects with increased pulmonary flow. The transthoracic, apical view, Doppler echocardiogram was used, positioning the sample-volume at the lower pulmonary vein, 4mm from its junction with the left atrium. The data analyzed included: dominant systolic or diastolic pulmonary venous flow and atrial contraction waveform characteristics, designated as "A" for absent and "R" for reversed. RESULTS: The study included twenty-nine patients with a mean age of 29.9 ± 58.9 months, suffering from the following congenital heart conditions: interatrial and interventricular communication defects, patent ductus arteriosus, atrioventricular septal defects, total transposition of the great arteries and truncus arteriosus. All the patients presented a continuous pattern of high velocity pulmonary venous flow. Nine patients presented a dominant systolic waveform (31%), eighteen presented a dominant diastolic wave form (62%) and 2 patients had systolic and diastolic wave forms of equal amplitude (7%). Six patients (21%) presented a R atrial contraction waveform and 23 (79%) presented an A atrial contraction waveform. CONCLUSION: Congenital heart diseases with increased pulmonary flow present a continuous pattern of high velocity pulmonary venous flow with alterations mainly in the atrial contraction reversal pattern.
